VB252 is a dual input DVB-T/T2 input interface module that enables monitoring of digital terrestrial transmissions. Two modules may be housed in a 1RU chassis together with a controlling VB120 or VB220 probe, providing high monitoring capacity occupying a minimum of rack space.
In addition to monitoring typical RF parameters, the monitoring solution optionally allows advanced analysis of the complex T2-MI protocol; signal integrity is verified layer by layer. This analysis functionality is complemented by the renowned VideoBRIDGE ETSI TR 101 290 monitoring engine to ensure standards conformance at all levels.
DVB-T2 allows signal distribution to transmitter sites via IP in addition to synchronous distribution methods like satellite. The VB120/VB252 combination enables monitoring of up to 50 IP multicasts, thus monitoring IP network distribution together with DVB-T2 transmissions. It is even possible to equip the monitoring chassis with a VB272 satellite interface module, which is valuable if combined IP and satellite distribution to transmitter sites is used.
